I'm afraid the good ideas, such as they were, were completely buried under all the stupidity, annoying choppy editing and ludicrous hammy acting (and God, Kyra Sedgwick is ugly).
I was so appalled by the film I went and read some reviews. It seemed to pick up some praise for the "game-like" quality of the action scenes. That may be true - I'm not a gamer - but I found them so completely and utterly uninvolving I was very, very, tempted to fast-forward or just switch off altogether.
I suppose I should've known what to expect from the directors of Crank....
